Different-sized colliders in Unity change the angular velocity

I’ve been working on adding different playable spaceships to Escape the Sector, but I’ve noticed this curious feature in Unity (I thought it was a bug at first!).

Watch this video:

Even though these 3 ships all have the same mass, angular velocity, drag and the same force is being applied, they turn at different rates because they have different sized colliders.

I assume this is normal, but it’s going to make it quite difficult to get the turning speed the same on them all without a lot of tweaking!

New signs in Escape the Sector – Billboards in space!

Not incredibly exciting news, but a chance to show some screenshots of progress nontheless…

I thought Escape the Sector (for Android) needed some better instruction, specially on the later levels where it’s unclear which direction you need to go. I was going to leave it so the players can explore the level, and learn the direction through the maze, but it seemed to frustrate some people – probably because lots of red boxy cliffs look identical!

So I’ve added some signage, pointing to the exit.

As well as some new animated signs with the message to “Evacuate Evacuate”!

sign saying escape immediately

I’ve also created some new playable ships – so that I can create a player select screen.

Probably not quite as cool as the ships created by Dave Bisseg (see those here), which I’ll also add, but I just enjoy creating new ships in this boxy, voxel style!

Some more things to add to Escape the Sector…

I’m not done with Escape the Sector yet (which I released on the Google Play store in July). I toyed with leaving it a bit, and moving to another project, but I’ve been encouraged by a 3D artist called Dave Bisseg who contacted me after I posted screenshots on a Facebook group for Indie developers, and has created some new ships, which perfectly fit the blocky, voxel style of what I’ve already created.

For comparison and to show what a great job he’s done at matching the style, here’s one of my large ships (originally made for the abandoned Escape Vector project).

Debrief of my “Escape the sector” game project

Ok, this might not be of much interest to anyone other than me, but as I’ve been writing other stuff about my game here, it seems like a good place to put it. So I’ve spent a long time on Escape the sector, which is unfortunate because if you actually play it all the way through, 6 levels lasting 2 minutes it’ll only take you 12 minutes. I feel like the effort / play ratio is way off! 😛

Dragging a file to applications to install on Mac is a great paradigm, but baffling the first time you do it

On a Mac, it’s common practice to install something by dragging a file to the applications folder. From my Windows background, I’ve always known installing things to be different. You click a downloaded executable, wait for the installer to run, choose a directory, and then it tells you it’s installed. Fine. Good. Done. Groovy.

But on Mac it’s different. You download a DMG file (no idea what that stands for, but I literally don’t care. I just want it to work), then double-click it, and fine, that’s all the same. And then, things get a bit different depending on the app, but I’ve noticed that mostly all apps will show you something like this:

drag to install on a mac

Which when you first see it, might be totally baffling. Nowhere tells you what to actually do, and I was confused the first time I had to do this. Luckily I had someone nearby who’s been using a Mac for long enough to tell me to drag the icon on the left onto the one on the right.

Sensible, really, because it’s symbolic of you dragging an individual app into your Applications folder. I like that, but I feel like some instructions are needed, in case this is the very first time you’re installing something! This one by PhoneGap is quite good because at least it’s instructive. install phonegap

Not all drag to install processes are the same either, here’s a few other examples:

install firefox

install google drive

The difference of design makes me assume that this isn’t a necessity, and is a convention perpetuated by app creators. I’m sure I’ve seen some where you have to drag vertically, and some where you just have to click.

That time I made a boring but useful green arrow

A while ago I needed an arrow in one of my 3D hobby projects, I think it was for Starbug Thruster but can’t remember. Anyway I was surprised that I couldn’t easily find such a basic 3D shape, so made one myself and put it on Turbosquid (see it here). Other arrows do exist of course, but have a high poly-count (not good for games) or are expensive, like this one which seems a bit steep at $8.

Anyway over a year later my arrow has been downloaded over 19 thousand times, and I received this really nice email from someone who used it: Continue reading That time I made a boring but useful green arrow
